        <h1>Navbar导航示例</h1>
        <p>This example is a quick exercise to illustrate how the navbar and its contents work. Some navbars extend the width of the viewport, others are confined within a <code>.container</code>. For positioning of navbars, checkout the <a href="../navbar-top/index.html">top</a> and <a href="../navbar-top-fixed/index.html">fixed top</a> examples.</p>
        <p>At the smallest breakpoint, the collapse plugin is used to hide the links and show a menu button to toggle the collapsed content.</p>
